Earth-616, ( he answers easily, as if the whole multiple dimensions thing is entirely normal and everyone's heard of it. which isn't quite true, but--listen: he's been dimension hopping for so long, it a lot more normal to him now than it would have been before. he follows chase's eyes down to his costume, gives a sheepish smile in response as he drops his hand back down to his side. the costume shimmers, blue magic energy covering it as it shifts into something more--normal. a t-shirt and jeans, rather than the billowy cape and stars. ) And 2013? Timelines can definitely get complicated with multidimensional travel, haha.

( trust him, billy's been around the block. more than once. he's been stuck in a few loops too which is never pleasant. and parasitic dimensions, ones full of kree and skrull overlords, ones where there are barely any heroes left. . it's Complicated. )

The room's a little plain, isn't it? How many roommates do we have?
